Asian parasites and hornets … because of these scourges, the population of bees fell in Belgium, and this is not good news

Asian parasites hornets … because: This article explores the topic in depth.

Therefore,

Asian parasites hornets … For example, because:

The population of bees in Belgium fell by 22.5 % in last winter. Moreover, it arises from a survey published Monday by the Honeybee Valley platform of the University of Ghent (Ugent). &#13. Consequently,

Research was carried out in collaboration with the Walloon Center for Agronomic Research (CRA-W) and the Cari APICOLE ASBL.

As part of the investigation, some 710 beekeepers were questioned throughout Belgium. Consequently, Together, they saw 1,679 bee colonies disappear during last winter. Additionally, Consequently, “A 10 % winter mortality rate is considered normal,” said Ellen Danneels, conservative beekeeper at Honeybee Valley. “With an average of 22.5 %, we are therefore much above, but it is not an asian parasites hornets … because extreme figure. These data obviously do not delight Honeybee Valley. although beekeepers expect each year that part of their colonies does not survive in winter. Bee populations have been declining for several years in Belgium. In 2024, the mortality rate of bee colonies amounted to 22.3 %, after 17 % in 2023.

Ellen Danneels identifies two main factors likely to explain this high winter mortality. The Varroa Destructor mite is particularly harmful for bee colonies. This parasite weakens the bees, making them very vulnerable. According to the survey, 45.3 % of beekeepers are trying to fight against this invasive species by treating their hives with oxalic acid. commonly known as sorrel salt.

The decline of bee colonies can also be linked to asian parasites hornets … because Asian hornets. another increasingly widespread invasive species in Belgium in recent years. Almost one in ten beekeeper discovered empty hives after an attack on Asian hornets. However, “we are not sure that the hornets are directly responsible for winter mortality,” said the scientist. “It seems more likely that they are more problematic in the spring. »»

Brussels, a region which has the smallest bee population, has also recorded the highest mortality rate, with 44 %. Conversely, in Flemish Brabant, which concentrates the largest population of bees in Belgium, the latter only declined 7.9 % last winter.
